To all whom it may concern/:

Be it known that we, THOMAS MCCORMICK and ANANIAS D. MILLER, citizens of the United States, residing at Mount Pleasant, in the county of Westmoreland and State of Pennsylvania, have invented a new and use ful Carbureting Device for Explosive-Engines,of which the following is a specification.

This invention relates to improvements in carbureting devices for gas or vapor engines, but more particularly toa novel carbureting attachment by means of which the Huid-pres` sure generated Within the cylinder of the engine is used in the form of exhaust-gases to operate the `oarbureter for the purpose of supplying a hydrocarbon vapor to the explosionchamber of the engine and also tothe burner utilized to heat the ignition-tube.` f

Considered in a more specific aspect,the object of the invention isvto utilize the exhaust of a vapor-engine for the purpose of producing and feeding the vapor, under pressure, to the explosion-chamber andburner, the exhaust being forced by its o wn expansive energy through one or more carbureting-chambers for enrichment before being returnedto the explosion-chamber and ignition-burner, as stated. Y

A still further object of the invention is to so equip or construct the oarbureter that the exhaust will be conducted through the oilchamber of the carbureter to heat and partially vaporize the oil before being liberated within the carbureting-chamber for enrichment.

Still further and subordinate objects of the invention will hereinafter more fully appear as the necessity for their accomplishment is developed in the succeeding description of the preferred form of our invention, illustrated in the accompanying drawings.

In saiddrawings, Figure 1 is'an elevation of an engine with our carburetor attached thereto, the latter being shown in section,and Fig. 2 is a detached view of thev oarbureter on asomeWhat-enlarged scale. Fig. 3 is a detail sectional vievvillustratingv the construction and mounting of the Wicks and Wick-tubes.

Referring to the numerals employed to designate corresponding parts throughout the views, 1 indicates'the cylinder of a vapor-engine; 2, the supply-pipe through which the explosive vapor is supplied to the cylinder; 3, the exhaust-pipe, and 4 the ignition-tube, designed to be heated to a state of incandescence by the ignition-burner 5. The operation of engines of this type, which of course include a piston 6 within the cylinder, is Well understood in the art, and it need only be stated that the explosive vapor or gas is fed to the interior 'of the cylinder through the pipe 2 and is compressed by the return stroke of the piston and forced back under compression into the incandescent tube 4:. The intense heat of the tube explodes the vapor, which drives the piston 6 to the opposite end of the cylinder and iinally exhausts through the exhaust-pipe 3. Our invention is particularly applicable to engines of this type; but it will be evident as the description progresses that the application of the principle of the invention is possible in connection with motors of various other types.

Located at .any suitable point, but prefer- I ably immediately adjacent to the engine, as shown, I provide a metal casing 7, subdivided by two horizontal partitions 8 and 9 into an exhaust-chamber 10, a gas-compartment 11, and an intermediate oilcompartment 12. The compartments 11 and 12 are further subdivided by a central vertical partition 13, at the opposite sides of which are defined the carbureting-chambers 14 and 15 and the superposed vapor and gas chambers 16 and 17.

.Within thev carbureting-chambers 14: and 15 are provided a number of preferably cylindrical wicks 18, preferably surrounding wicktubes 19 and having their upper ends extended through thimbles4 20, screwed into suitable openings in the partition 9. The Wick-tubes 19, which are shorter than the Wicks, are located in the upper ends thereof for the purpose of preventing their collapse and also for the purpose of spreading the wicks against the inner faces of the thimbles with sufficient pressure to insure the retention of the upper ends of the Wicks by the thimbles in order, to prevent the possibility of the dropping of the former when they become saturated with oil-that is to say, the Wick-tubes act as spreaders, which tend to prevent the clogging of the upper ends of the wicks and at the same time assist in the retention thereof within the thimbles.

For the purpose of introducing the liquid hydrocarbon to the carbureting-chambers 14 and 15 we provide filling-tubes 21 and 22, extending through the top of the casing and through the partition 9, and after utilizing these tubes for the purpose indicated they are coupled by means of short sections of hose 23 or by other suitable means to the upper ends of heating-tubes 24 and 25. These heatingtubes, like the filling-tubes 21 and 22, extend through the top of the casing, but are of suficient length to extend down through the compartments 11 and 12 and through the partitions 9 and 10 for the purpose of placing said tubes in communication with the exhaustchamber 10. If desired, the hydrocarbon may be introduced through the filling-tubes Without moving the hose-sections by providing the latter with suitable filling-valves 26, as shown.

Inasmuch as it is designed to supply the burner 5 and the cylinder l with combustible vapor from the carbureter described, the latter is provided, preferably in its top wall, with pipe connections 27 and27, opening into the vapor-chambers 16 and 17, and designed, respectively, for connection with the burner supply-pipe 28, leading to the burner 5, and the supply-pipe 2, leading to the cylinder of the engine. The pipes 2 and 28 are provided, as usual, with controllingvalves 2S, as shown, for the purpose of controlling the passage of vapor to the explosion-chamber and ignition-burner, respectively.

At one end of the exhaust-chamber 10 we provide a pipe connection 29, controlled by a valve 30 and coupled to the exhaust-pipe 3 of the engine. At the opposite end of the exhaust-chamber 10 is provided a petcock3l, by means of which a portion of the exhaust may be permitted to escape in order to prevent undue1 compression within the carbureter.

Assuming the device to be equipped and connected to the engine in the mannerstated, its operation is as follows: The temperature of the exhaust fluid is very high, and as it is forced from the explosive-chamber of the engine into the exhaust-chamber 10 through the pipe 3 it will escape from said chamber through the heating-tubes 24 and 25. Inasmuch as these tubes are located within the carbureting and vapor chambers, they will serve as vaporizers for the purpose of permitting the use of crude or heavy oils and will serve to raise the tension of the vapor after it has passed from the carbureting-chambers into the vapor-chambers 16 and 17- that is to say, the heated exhaust passing through the tubes 24 25 will irst heat the oil within the chambers 14 and 15 and will then heat and raise the tension of the vapor which has passed into the chambers 16 and 17 from the carbureting chambers. Having performed this office, the exhaust will pass through the hose-sections 23 and through the filling-tubes 22 for delivery to the carbureting-chambers 14 and 15. It will now be seen that the exhaust in order to escape from the carbureting-chambers must penetrate the oilladen wicks 18, which will obviously carburet the Huid and form a combustible gas, which escapes into the vapor-chambers 16 and 17 and is finally delivered under more or less pressure through the pipes 2 and 28 to the cylinder of the engine and to the burner 5, respectively. Thus it will appear thata complete cycle of utilityis established, inasmuch asthe exhaust from the engine is employed to force fluid through the carbureter for the formation of a combustible gas subsequently supplied to the explosion-chamber and ignition-burner of the engine, the exhaust being also utilized for the purpose of heating the oil and of raising the tension of the vapor prior to its delivery. In conclusion it may be stated that the heated Huid passing into the carbureting-chambers under pressure is passed into the vapor-chambers; but in doing so is compelled to pass through the saturated wicks, a portion of the fluid passing through the wicks around the tubes and another portion through the material of the wicks and up through the wick-tubes 19.

From the foregoing it will be observed that We have produced a simple, ingenious, and eective carbureting attachment for Vaporengines arranged to supply a combustible vapor to both the explosion-chamber and ignition-burner and operated by the exhaust of the engine; but while the present embodiment of the invention is believed at this time to be preferable, we desire to reserve the right to eect such changes, modifications, and variations of the illustrated structure as may be suggested by experience and experiment, so long as such changes are embraced within the scope of the protection prayed.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-
